Different measures used to define integrated care

Research question	Integration exposure measure	Definition	Notes
1) Does the Integra Intervention have an effect on HIV testing uptake among FP clients, compared with FP clients in facilities that did not receive the Integra intervention?	Design group	Attended intervention or comparison facility at the time of recruitment visit	6 intervention, 6 comparison facilities
2) Does the receipt of integrated RH‐HIV services during an FP visit increase annual HIV testing over the subsequent two years (regardless of study arm)?	Individual receipt of integrated services at baseline	Woman received a combination of at least one RH service (FP, MCH) and one HIV/STI service (HIV testing, HIV counseling, STI service) during her consultation at baseline	Binary measure (yes/no). HIV testing uptake measured at Rounds 1–3 only (baseline excluded)
3) Does the level of integration at the facility lead to an increase in annual HIV testing among FP clients (regardless of study arm)?	Baseline facility integration index score	Score derived from Integra Functional Integration Index (IFII) to measure the extent of integration at the facility level	Low (≤1.99), medium (2.00 to 2.74), or high (≥2.75) index integration score
4) Does the cumulative score for the level of integration in all facilities visited by a woman over two years influence her uptake of annual HIV testing?	Cumulative integration index score	Cumulative index exposure (additive score) to capture subsequent visits at study clinics	Grouped by tertiles of cumulative score into low, medium, and high.
